Patent CA-2788836-A1 (CA)
Inventor: RHOADS GEOFFREY B
IPC: H04M1/72403
Filed: 2011-02-23
Abstract: A smart phone senses audio, imagery, and/or other stimulus from a user's environment, and acts autonomously to fulfill inferred or anticipated user desires. In one aspect, the detailed technology concerns phone-based cognition of a scene viewed by the phone's camera. The image processing tasks applied to the scene can be selected from among various alternatives by reference to resource costs, resource constraints, other stimulus information (e.g., audio), task substitutability, etc. The phone can apply more or less resources to an image processing task depending on how successfully the task is proceeding, or based on the user's apparent interest in the task. In some arrangements, data may be referred to the cloud for analysis, or for gleaning. Cognition, and identification of appropriate device response(s), can be aided by collateral information, such as context. A great number of other features and arrangements are also detailed.

Title: Small-molecule hydrophobic tagging of fusion proteins and induced degradation of same
Inventor: CREWS CRAIG M
IPC: A61K31/7076
Filed: 2011-12-06
Abstract: The present invention relates to the ability to regulate any protein of interest in living systems with small molecules. In particular, the present invention relates to the discovery that appending a hydrophobic moiety to the surface of a protein can mimic the partially denatured state of the protein, thus engaging the cellular quality control machinery to induce its proteasomal degradation. An aspect of the present invention relates to bifunctional small molecules that bind a number of proteins, including, for example, a self-labeling tag such as bacterial dehalogenase (HaloTag protein) and present a hydrophobic group on its surface. Hydrophobic tagging of the HaloTag protein with a hydrophobic moiety (e.g. an adamantyl moiety) was effected and the tagging induced the degradation of cytosolic, isoprenylated, and transmembrane fusion proteins in cell culture. The present invention also demonstrated the in vivo utility of hydrophobic tagging by degrading proteins expressed in zebrafish embryos and by inhibiting RasG12V-driven tumor progression in mice. Therefore, hydrophobic tagging of HaloTag fusion proteins affords small molecule control over any protein of interest, making it an ideal system for validating potential drug targets in disease models.
